Community businesses across England can apply for funding of between £10,000 and £150,000 to help reduce their energy costs. The funding, which is a mix of grants (up to 40%) and loans at 6.5% interest, can be used to cut energy use, lower bills, and improve the sustainability of community buildings. Support is available for projects such as installing solar panels or heat pumps, upgrading insulation, lighting, or heating systems, and fitting energy monitoring technology. Applicants must own their premises or hold a lease of at least 12 years and have been declined by a bank for commercial finance. Energy audit grants of £500–£2,500 are also available to identify potential improvements. The fund is delivered by Key Fund and financed by Power to Change through the Energy Resilience Fund.
